When no one is looking, a particle has near limitless potential: it can be nearly anywhere. But measure it, and the particle snaps to one position. How do subatomic objects shed their quantum weirdness? Experts in the field of physics, including David Z. Albert, Sean Carroll, Sheldon Goldstein, Ruediger Schack, and moderator Brian Greene, discuss the history of quantum mechanics, current theories in the field, and possibilities for the future.

This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation.

“My chances are 50-50. Not great odds. And that’s only to get to the starting line. The human race is not for the faint hearted, when half the runners are doomed to die, before the race gets started.”

This documentary film explores the development of the growing fetus from conception to delivery. Open a window into the hidden world of the foetus and explore each trimester in amazing detail. It’s meant to be a joyous event, but in reality, it's a gripping battle for survival. Using cutting edge technology, we go inside the womb and follow the incredible nine month journey from conception to birth, showing how the struggle for life turns into the miracle of birth. Enhanced by poet Roger McGough’s reading of a series of poems written for the occasion.

“Until now, I thought I was the universe. But everything that is, was within me. Now that I can touch these walls, I realise I must be deep inside a greater universe.”

This is a slide presentation by Prof. Ampim in a series of radio broadcasts on the ancient Kushite civilization, based on his extensive primary research in northeast Africa over the past 30 years.

Paul Andersen explains how populations eventually reach a carrying capacity in logistic growth. He begins with a brief discussion of population size ( N ), growth rate ( r ) and exponential growth. He then explains how density dependent limiting factors eventually decrease the growth rate until a population reaches a carrying capacity ( K ). A mathematical simulation of this process is included along with a brief discussion of r and K selected species.

According to our best theories of physics, the fundamental building blocks of matter are not particles, but continuous fluid-like substances known as 'quantum fields'. David Tong explains what we know about these fields, and how they fit into our understanding of the Universe.
